How many wall assemblies has Quik-Therm tested to ASTM C1363.

Over 30 wall assemblies have been tested to C1363. Results of these tests provide valuable data. This data allows QT to accurately estimate/model the effective R-value for many different thicknesses and types of wall assemblies.

  QT Thermal Testing Summary

 


Why did Quik-Therm choose the Effective R-value test method ASTM C1363, while other insulation manufacturers test their products for nominal R-value ie: ASTM C518?

Quik-Therm has tested to ASTM C518 (labeled R-value) and ASTM C1363 (effective R-value). New Canadian energy codes mandate the use of effective R-value. Since effective R-value is the standard, QT chose the test method based on the standard.

Solar Dry has a 3/16” deep drying plane gap occupying 80% of the panel. By having this gap, how much R-value is actually lost?

Tested to ASTM C1363 - Intertek/ATI compared two identical empty cavity wood fame wall assemblies. Wall 1: 2” QT Multi Purpose Insulation (no gap). Wall 2: 2" QT Solar Dry (3/16" gap). Results virtually identical: Effective R-13.2.

Does Building Science support the use of Solar Dry?

Yes. QT Solar Dry was developed based on findings by the Building Science Corporation (BSC).

  Drainage and Drying Planes

 


Does ASHRAE support the use of Effective R-values?

Yes. ASHRAE 90.1, Table A3.1D (as an example) lists Effective R-values for insulation and framing in above and below grade walls.

  A3-1D Table        Use of Effective R-value

 


Can ASHRAE effective R-values for cavity filled walls be added to QT effective R-values?

Yes. Example: ASHRAE Table A3.1D states R-12 fiberglass with wood studs performs effectively at R-9.8. As per C1363 test results, 2” QT performs effectively at R-13.2. Combining the ASHRAE fiberglass results and QT results together = Ru-23. To support Ru 23, QT tested this blended wall assembly to C1363. Result R-23.1. Note: The fiberglass insulation was R-13, not R-12. Potential Ru discrepancy less than R-1.

Is a double vapour barrier created by adding QT Connect or Multi Purpose Insulation (MPI) to a wall with a poly vapour barrier and batt insulation? Can double vapour barriers work?

Yes & Yes. MPI and Connect are effectively impermeable. Therefore when designed in conjunction with an interior poly vapour barrier, a double vapour barrier is created. However, walls with double vapour barriers can work. The key is to ensure the thickness of MPI or Connect is sufficient to keep the wall cavity warm. By doing so, the risk of condensation is significantly reduced. The thicker the exterior insulation, the warmer the cavity. The warmer the cavity the less chance for condensation.

  Double Vapour Barriers Can Work        In-Outboard Ratio

 


Tested to ASTM C518, what is the nominal R-value for QT Type 1 & Type 2?

Type 1 (T1) = R-3.81 / Type 2 (T2) = R-4.18.

 


Why does Quik-Therm recommend T1 for some products and T2 for others?

Type 1 (T1) is used in products where softer material with less compressive strength is an asset. Type 2 (T2) is used where higher compressive strength is required. Examples: T1 is better suited for interior and exterior below grade concrete walls and basement floors. When insulation fits tight to a concrete wall, its effective R-value is enhanced. Concrete walls are typically rough with many imperfections. Since T1 is mouldable (pliable) it seals tighter to concrete than higher compressive strength insulations.

On the other hand, because T2 has a higher compressive strength than T1, T2 is better suited for Solar Dry (SDI). Fastening furring materials over SDI applies significant pressure. Since T2 has higher compressive strength than T1, the drying plane channels maintain a minimum 1/8” deep cavity.

What benefits do QT’s reflective polymer facers provide?

•  Increase durability. QT does not easily chip, crack or break.

•  Provides two impermeable barriers. With proper detailing (taping), some QT products meet code compliance as part of an air, vapour and/or radon barrier system. See "In The News" - Canada's Largest Passive House.

•  Enhances the Effective R-value of assemblies.

•  Generally provides an additional line of defence (e.g. WRB) as outlined by Canadian building codes.

Stabilizers

Q. Should plastic stabilizers be adhered into slots with spray foam or adhesive?

No - but you can if you want. CIS utilizes an engineered metal grid framing system. Top angles are mechanically fastened to upper floor joists or concrete ceiling (concrete type buildings) and bottom angles are mechanically fastened to concrete floors. In-turn, L-studs are fastened to bottom and top angles. Stabilizers are supported by CIS foam panels and L-studs. Once drywall is fastened to the metal grid, advanced structural integrity is achieved.

Q. If I require stabilizers in places where there are no slots, what do I do?

You can install stabilizers anywhere by simply cutting minimum 1.5” deep by 2” wide slots in foam panels. Insert stabilizers into slots.

Q. What do I use if I run out of stabilizers?

Snip left over angles to 4.25” long. Bend over at corner so angle becomes flat (doubled up). Puncture film with corner of metal. Insert a small amount of spray foam. Insert fabricated stabilizer into foam panel slot until it bottoms out. Attach L-stud to stabilizer.

 



L-Studs / Angles & Foam Panels

Q. What do I use if I run out of angles/L-studs?

Quik-Therm CIS is a universal framing system. You can substitute metal angles for 2.5” deep metal studs or 2” x 3” (2.5” deep) wood framing/studs. Stabilizers can be fastened to wood or steel.

 


Walls & Floors

Q. Can a large flat screen TV be installed on Quik-Therm CIS walls?

Yes. A flat screen TV, up to 70 pounds (32 kg) can be attached directly to L-studs using authorized mounting brackets. The bracket must be mounted according to manufacturer’s instructions and mechanically attached to at least three L-studs (minimum 48” coverage). Per manufacturer’s instructions, for TV’s under 40 pounds (18 kg), the mounting bracket must be mechanically attached to two L-studs.  For heavier items see below.

Q. How do I support heavy items/shelves, etc. on CIS walls?

Prior to drywall, assuming you know where you want shelves, etc. it’s easy to attach additional steel or wood framing to L-studs, upper floor joists or on top of the concrete floor. Wall support can also be added on the outside after drywall is in place. If you are inexperienced with wall construction, we recommend you consult a building professional.

 

NOTE: Quik-Therm Insulation Solutions Inc. assumes no liability from accidents caused by items or articles attached directly or indirectly to Quik-Therm CIS wall panels and/or framing.

 

Q. Should I leave a space (gap) between the top angle and upper floor joists to allow for floor heaving?

No; a gap is not necessary. When basement floors heave, they don’t move upward uniformly. For conventional wood framing, the purpose of the gap is; - should a basement floor heave, the wood framed wall can’t lift the floor above. When a basement floor heaves upward it doesn’t move uniformly. A gap between the metal angle and floor joists will not stop drywall cracking.

Q. What happens to Quik-Therm CIS walls if a basement floor heaves upward?

Under upward pressure, CIS foam base gaskets and panels will compress, acting together as a shock absorber. This reduces some potential for drywall cracking. Most importantly, should major floor heaving occur, CIS will not lift the floor above.

Q. How do I level/plumb severely uneven walls?

Walls severely out of plumb (3 inches or more), require longer fabricated stabilizers made from angle off cuts. These stabilizers will need to be mechanically fastened to floor joists. For severely out of plumb walls we recommend you consult a building professional. See L-Stud / Angles.


Stone / Rough Surface Foundations

Q. How do I install CIS in a rough stone basement or Heritage building?

Instructions as follows:


1. Construct 2” x 3” wood frame walls - 24” O.C. Walls should be a minimum 1” shorter than existing wall height.

2. Wood framed wall to be as close as possible to existing wall. Ensure wood wall is straight, level and plumb.

3. Using long nails fasten top plate to bottom of floor joists. There will be a small gap between upper floor joists and top plate. For structures with concrete floors above, use Tapcons or equivalent fasteners.

4. Using Tapcon screws or equivalent, attach bottom plate to floor.

5. As per general instructions install foam base gasket.

6. Start in a corner and fasten foam panel to wood framing - as follows. Insert deck screws through plastic washers. Screws need to be 1.5” longer than thickness of foam panels and spaced approximately 16” apart.  **Plastic washers are available from Quik-Therm, or you can improvise with other washers. Thin pieces of plywood can also work as washers.

7. Following general instructions install all foam panels.

8. As per general instructions install stabilizers, bottom and top angles, L-studs and drywall.


Window and Door Framing

Q. Should I use metal angles or wood for framing windows and doors?

It is your choice, both work well. An advantage for metal angles is they can be bent, cut and shaped to fabricate all sorts of connection points for drywall.

Q. How do I finish/frame around windows and doors?

With CIS you can use wood or CIS L-studs for framing around openings. Are you doing decorative wood or drywall returns; or something else? Framing and finishing around openings with CIS is similar to conventional framing and finishing methods.


Drywall

Q. How far can I float drywall in corners without support?

You can safely float drywall (no framing required) up to 8 inches. However, if you prefer reinforced corners, we suggest you use pieces of leftover angle. Using drywall screws, behind one end of drywall, fasten a piece of angle. Fasten adjoining sheet of drywall to opposite side of angle.

Q. How do I install drywall at corners?

Method 1: At corners, lay in place drywall so that sheet edges butt (overlap) together. Measure from edge of drywall to middle of fourth L-stud and cut drywall to this length. Fasten drywall to L-studs and angles. Do not discard drywall off cuts; they will be needed elsewhere.


Method 2: Pre-cut corner foam panels so drywall (8” drywall) spans from corner L-stud(s) 96” to center of the fifth L-stud stud. Note# Foam panels are more expensive than drywall and it takes longer to cut foam than drywall. Should you decide to cut foam panels for corners; at least one additional foam panel will be needed.
